Unsp injury of radial artery at forarm lv, unsp arm, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to the radial artery in the forearm. The initial injury is no longer acute, and the patient is experiencing residual issues related to that past trauma, such as chronic pain, nerve damage, or impaired circulation. The specific nature of the original injury and the affected arm are not documented.

This code is appropriate when a patient presents with a current condition directly attributable to a previous, unspecified injury of the radial artery in the forearm. This would include follow-up visits for chronic pain, functional limitations, or other persistent sequelae after the initial healing phase of the original injury has passed. It should be used when the specific side of the body is not documented.

• Always assign a sequela code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, nerve palsy).
• Ensure documentation clearly links the current condition to a past radial artery injury in the forearm.
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code from the S55 category.
